Conditional sql based on string content

How to judge an image url that if the link contains words ads ad, then pass insert into the database. Then it should be insert into first data, and pass the second one. Thanks,

PHP CODE

foreach($data['image'] as $item) {
  $title = $item['title'];
  $image = $item['image_url'];
  mysql_query("SET NAMES utf8");
 mysql_query("INSERT INTO article (title, image) VALUES ('".$title."', '".$image."')");
}

JSON TREE

{
    "image": [
        {
            "title": "the big lake",
            "image_url": "http://localhost/json/image/the_big_lake.jpg"
        },
        {
            "title": "Nike Air",
            "image_url": "http://localhost/json/image/12087689_ads.jpg"
        }
    ]

I'll assume you want to insert all images that do NOT have "ad" in the image url... if you want ONLY ads, change the === in the if statement to a !==. Make sure to keep it as either a triple-equals or exclamation-double-equals.

Also note that this is not a very reliable method - what if the image were called "my_dad_and_mom.jpg". It contains "ad", but is not an ad.

foreach($data['image'] as $item) {
  if (strpos($item['image_url'], 'ad') === false) {
    mysql_query("SET NAMES utf8"); // not sure why this is needed....
    mysql_query("INSERT INTO article (title, image) VALUES ('".$item['title']."', '".$item['image_url']."')");
  }
}

EDIT: This is sort of quick and dirty...

    $forbidden_words = array(
        'ads',
        'ad',
        'sex',
        'xxx'
    );
    function str_in_array($str, $array) {
        foreach ($array as $token) {
            if (stristr($str, $token) !== FALSE)
                return true;
        }
        return false;
    }
foreach($data['image'] as $item) {
  if (str_in_array($item['image_url'], $forbidden_words) === false) {
    mysql_query("SET NAMES utf8"); // not sure why this is needed....
    mysql_query("INSERT INTO article (title, image) VALUES ('".$item['title']."', '".$item['image_url']."')");
  }
}

like this?

foreach($data['image'] as $item) {
  $title = $item['title'];
  $image = $item['image_url'];
  if(preg_match('/ad/',$image){
    mysql_query("SET NAMES utf8");
    mysql_query("INSERT INTO article (title, image) VALUES ('".$title."', '".$image."')");
  }
}
